This is unique source of information on the chemicals manufactured and imported in Europe. It covers their hazardous properties, classification and labelling, and information on how to use them safely.

However, refineries use a variety of process plants operating under different conditions. The chemical composition of crude oil feedstocks also varies widely, so the type and quantities of different hydrocarbons present in output streams from the same manufacturing processes can vary both within and between refineries.
